FILLING-CARRIER FOR AUTOMATIC FEELER-LOOMS.

SPECIFICATION forming part of Letters Patent No. 764,606, dated July 12,1904.

Application filed April 14;, 1904.

To (all whom, it may concern.-

Be it known that I, OINoINATUs I-I. LAND, a citizen of the UnitedStates, residing at Knoxville, in the county of Knox and State ofTennessee, have invented an Improvement in Filling-Carriers forAutomatic Feeler-Looms, of which the following description, inconnection with the accompanying drawings, is a specification, likecharacters on the drawings representing like parts.

This invention has for its object the production of a novelfilling-carrier or bobbin for use in the shuttles of automaticfeelerlooms wherein the operation of filling-replenishing mechanism iseffected by or through the action of a feeler instrumentality upon thesubstantial exhaustion of the filling in the shuttle.

Different forms of feeler-looms are shown in United States PatentsNos.685,236, 7 25,194, and 725,229, as well as in various other patentsof later dates,all being distinguished,however, by a feeler whichintermittingly cooperates with the filling in the shuttle and causes thereplenishment of the running filling prior to complete exhaustion of thesupply in the shuttle. As is well known to those skilled in the art,enough filling must remain on the filling-carrier at the time the feelerinstrumentality is caused to operate to extend one or more times acrossthe lay to prevent a mispick. This filling is wound upon the barrel toform a preliminary winding or bunch, and then the main winding is laidon each side of and over the bunch. hen the yarn behind the bunch isweaving oil, it is very apt to catch upon the bunch as it is drawn overit and frequently breaks, causing considerable waste.

In accordance with my present invention the barrel of thefilling-carrier is provided with a section adapted to receive apreliminary bunch or winding of yarn during the spinning operation, andbetween said section and the head of the filling-carrier the barrel isprovided with a substantially cylindrical section of larger diameter toreceive the yarn behind the bunch, the external diameter of Serial No.203,067. (No model.)

the latter being, substantially that of the larger section. hen the yarnis woven oil this larger section back of the bunch, it draws freely overthe bunch, owing to the greater diameter of the section, so that thereis no chance for it to catch on the bunch, and consequently the tendencyof the yarn to break 1 by catching on the bunch is completely obviated.Any Waste yarn left on the bunch-receiving section can be readily slidoff by the attendant and removed from the bobbin without the use of aknife or other cutting implement.

Figure l is a view in elevation of a fillingcarrier embodying myinvention and showing the preliminary bunch or winding of yarn thereon,and Fig. 2 is a longitudinal sectional view of the filling-carrier.

The filling-carrier comprises a barrel 1, having a longitudinal centralspindle-receiving bore 2 and an enlarged head or base 3, provided Withannular projections or rings 4-, adapted to be engaged by holding-iawsin a shuttle in well known manner. Adjacent the head the barrel 1 isprovided with a substantially cylindrical section 5, and contiguous thesaid section is a bunch-receiving section 6 of less diameter, alsosubstantially cylindrical. In the spinning operation a preliminary bunchor winding? of yarn is laid upon the section 6, containing sufiicientyarn to extend across the lay of the loom one or more times, ample yarnbeing thereby provided to prevent a mispick. This bunch is built up tosubstantially the diameter of the section 5, the two sections beingstepped, and then the main Winding is begun and the yarn mass is laid asusual, its outline being indicated by dotted lines, Fig. 1. In operationthe feeler intermittingly engages the yarn mass, and so long as thediameter of such mass is greater diameter of this section is such thatthe feelcr instrumentality will thereupon operate and cause theactuation of the filling-replenishing mechanism; but there will be ampleyarn remaining in the bunch to last until a fresh supply of filling isprovided.

By having the bunch or preliminary winding 7 at the outer end or behindthe section 5 there is no opportunity for the yarn wound upon saidsection 5 to catch upon the bunch and break, for none of this yarn canbe wound upon a diameter equal to or less than that on which the bunchitself is wound. Of course the diameter of the section 5 is such thatwhen bared of yarn the feeler will operate, there still remaining enoughyarn in the bunch to extend several times across the lay. By having thelarge diameter of the section 5 the yarn spun thereon tends to have moretwist and to be stronger than would otherwise be the case, and this isof value, as the nearer the yarn to the head of the filling-carrier whenweaving off the greater is the strain thereon.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A filling-carrier for feeler-looms, comprising a head, and a barreladapted to receive on its largest diameter a preliminary bunch, orwinding of yarn, and an enlarged, substantially cylindrical sectionbetween the head and bunch receiving section of the barrel, whereby theyarn wound at the bunch and behind the same will weave olf withoutbreakage.

2. A filling-carrier for feeler-looms, comprising a head, and a barrel,the latter having at the head end two contiguous and substantiallycylindrical sections of different diameter, the section of largerdiameter being nearer the head and adapted to cause the operation of afeeler instrumentality prior to the exhaustion of the yarn in apreliminary bunch or winding adapted to be laid upon the smaller sectionin the spinning operation, the yarn wound upon the larger sectionweaving off over the bunch without catching thereon.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
